调用TransferFrom函数，转入转出账户相同，请问是我的代码有什么问题吗

const linkContract = new web3.eth.Contract(contractABI, contractAddress);
export default {
  methods: {
    async approveLink() {
      let result = await linkContract.methods
        .approve(authAddress, "10")
        .send({ from: walletAddress });
      console.log(result);
    },
    async transferFrom() {
      let result = await linkContract.methods
        .transferFrom(walletAddress, authAddress, "10")
        .send({
          from: authAddress,
          gas: "100000",
        });
      console.log(result);
    }
}
